cement kiln dust soil stabiliation

Ash Grove Resources, L.L.C. providescementandcement kiln dustto the construction industry and offers products for various applications, such as drying out wet soils,soiland aggregatestabilization, Full-Depth Reclamation (FDR), aggregate basestabilization, and pavement sub-bases. The company

Stabilizationcan be used to treat a wide range of sub-grade materials, varying from expansive clays to granular materials. This process is accomplished using a wide variety of additives, including lime, fly-ash, and Portlandcement. Other material byproducts used inStabilizationinclude lime-kiln dust(LKD) andcement-kiln dust(CKD).

Stabilizationof soils is an effective method for improvingsoilproperties and pavement system performance.Cement kiln dust(CKD) represents an alternative to the traditionalstabilizationagents of lime,cement, and Class C fly ash. As with the other additives,cement kiln dustcan be expected to vary in effectiveness depending on thesoiltype.

The activator content is generally in the range of 20 to 30 percent of the fly ash used to fill the voids. The activator is normally either lime or Portlandcement, but limekiln dustorcement kiln dustcan also be used. Similarly, consider a claysoilthat is stabilized with lime but the clay is not pozzolanically reactive.

A laboratory study was undertaken to evaluate the effectiveness ofcement kiln dust(CKD) as asoilstabilizer. The study revealed that increases in the unconfined compressive strength (UCS) ofsoiloccurred with the addition of CKD. Increases in UCS were inversely proportional to the plasticity index (PI) of the untreatedsoil.

The globally growing demand ofcementresults in towering collection ofkiln dustfromcementplants. The disposal of this finedustis very difficult and poses an environmental threat. To overcome this problem, research is being carried out in different parts of the world to find out economical and efficient ways and means of usingcement kiln dust(CKD) in various applications likesoil...

LimeKiln Dust, a.k.a LKD, is a byproduct created when manufacturing Quicklime. When limestone is naturally heated, it produces gas withdust. Thedustthat is screened out is called LimeKiln Dust. LKD, has little beneficial use, and is mostly disposed of into landfills. The site work industry uses LKD as a stabilizing agent to dry poor soils.

Successfulstabilizationhas been accomplished utilizing dry flue (kiln)dustfrom our plant air pollution control. This fluedustcontains 20 – 50% of calcium oxide, plus fly ash. Depending upon the amount of calcium hydroxide thesoilrequires, increasing the tonnage to compensate for the lower availability of lime in the fluedustwill ...

Quicklime and limekiln dustcan also be used to dry wet soils at construction sites, reducing downtime and providing an improved working surface. The application of lime can significantly improve the engineering properties ofsoil. There are essentially two forms of improvement:soilmodification andsoil stabilization.

Cement Kiln Dust. CKD (cement kiln dust) is effective insoil stabilizationprojects, extending the service life of our nation’s roads and parking surfaces. Formerly landfilled, creating a high-value use for this product is part of Ash Grove’s overall commitment to sustainable development. Available …

This research investigated the suitability ofcement kiln dust(CKD) on thestabilizationof clayeysoilextracted along a failed road section of Sango, Ota. Since CKD does not need any further processing or treatment, it is cheap as it is a waste product fromcementproduction and can be …
